Here's a link to it on the web: Weebalot Castle.
They have it listed for $39.99. I got it at Target (after Christmas sale) for $8.74. SCORE!! That's why she got such a big gift for Valentine's Day. That, and I was too excited to play with it to keep it until her birthday in April.
BTW, those are Little People Izzy has playing in it. The actual Weebles are really, really cute though!
